中文摘要:应用陀螺力学理论,对传统动力总成悬置系统的无阻尼动力学方程进行修正,引入陀螺矩阵,得到新的动力学方程。对新的动力总成悬置系统动力学模型进行计算分析,研究了陀螺矩阵对频域、时域响应的影响。使用遗传算法分别对修改前后的方程进行优化计算,并进行比较分析。结果表明,对于低转速发动机,曲轴转动的陀螺效应不明显,而对于高转速的发动机,陀螺效应不能忽略,应以考虑陀螺力矩的方程为基础进行设计分析。

Abstract: The traditional no-damp equation of a engine-mount system was modified with consideration of gyro effect. To indicate the effect of gyro moment on the mount system, including frequency domain response and time domain response, the new system was analyzed. The engine-mount was optimized for the traditional equation and the new equation, respectively, using the genetic algorithm. The results for two equations were analyzed and compared, which showed that the gyro effect of the crankshaft system could be ignored for low rotating-speed engine and it should be considered for higher rotating-speed engine.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
